SILL-PLATE FOR SHUTTER-FASTENERS.

Specification of Letters Patent.

Patented May 2e, 190s.

Application led August 17, 1907. Serial No. 389,059.

To all whom it may concern.'

Be it known that I, HARRY ZIMMERMAN, a citizen of the United States, and resident of Fremont, county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Sill-Plates for Shutter-Fas'- teners, of which the following is a specification.

' My invention relates to sill plates for shutter bowers and consists in making such plates in such form that sheet metal can be used in their manufacture with great advantage as to cost and finish.

In the accompanying drawing: Figure 1 is a perspective view of a sill plate embodying my invention Fig. 2 is a plan view of Fig. 1,' Fig. 3 is a longitudinal section; Fig.

' 4 a transverse section on the line 4 4, of

.The bridge Fig. 3,' Fig. 5 a plan showing a different form of sill late Fig. 6 a side view of the sill plate, lgig. 5, and Fig. 7 a section on the line 7 7, Fig. 5.

The sill piece consists of a single plate of sheet metal pro erly shaped, perforated and stamped into sliape to form terminal base pieces, l, 1, an intermediate bridge piece 2, and inclined connecting and supporting parts 3, 3. The base pieces l, 1 have perforations 4 for the passage of the fastening screws, and in order to provide proper tapering sockets for the concave screw heads a circular rib or bead 5 is raised round each perforation 4, which rib further stilfens the base piece so that the device may be made of thinner metal than would otherwise be needed. To the same end the bridge piece has at each side a dependent flange 6, and the supporting parts 3, 3, also have side flanges 7, whereby great stiffness is imparted with the use of light thin metal.

4To afford a wider base and better support for the bridge the base pieces l, l are wider than the bridge, the supports 3, 3, widening from the bridge toward the base pieces. piece has any suitable number and arrangement of sockets 8 for the catch or brace rod of the shutter bower. In Figs. l vto 4 there is a sin le row of sockets. In

Figs. 5to 7a sill p ate is shown in which there is a row of sockets and also two sockets side by side as is desirable in some cases, and in order to provide inclined faces on which the catch of the shutter may slide up and Adrop into its socket, the bridge has at the side opposite each such socket an inclined wing l0 formed by a downwardly inclined extension of the plate.

It will be seen that as the article is of sheet metalit may be stamped by proper dies from a single plate and at one or two operations of the dies, and that it is so formed that great strength is secured with the use of but thin light metal, the articles being thus manufactured at a small cost. It will also be evidentthat as sheet metal is used a much finer finish can be secured than by the use of cast metal as usual, while the loss in manufacturing which always results from a large proportion of imperfect castings is avoided.

Without limiting myself to the construction shown I claim:

l. A sill plate for shutter bowers consisting of a single piece of sheet metal having perforated terminal base pieces and an intermediate elevated socketed bridge piece,

the latter provided with independent side flanges for the purpose set forth.

2. A sill plate for shutter bowers consisting of a single piece of sheet metal having perforated terminal base pieces and an intermediate elevated socketed bridge piece, the latter provided with dependent side flanges, and outwardly extending inclined wings, for the purpose set forth.

.3. A sill plate for shutter bowers made of .sheet metal with perforated terminal base pieces, an intermediate socketed elevated bridge piece, and inclined end supports for the latter, the bridge piece and supports having dependent side flanges for the purpose set forth,

In testimony whereof I aflix my signature in presence of two witnesses.

HARRY ZIMMERMAN.
